Is there really RAM located at this address on your board? Address 0x40000 is usually only an example address...
It is very likely that there is RAM at this address. On PowerPC, RAM usually is mapped starting at physical address 0.
This is different per architecture, and not properly explained in the readme and the faq. Is the memory there really always free?
i start executing go 40004 command its not doing any thing.
You should use the the same address in the 'go' command as to which you load the executable.
This advise is almost certainly wrong - the entry point is usually not the same as the image's start address.
Indeed, it worked in our case on ARM properly, because the examples are compiled such that there are no symbols before the entry point... If a routine is added in the same file above the entry point, the entry point indeed moves. But, why is this information on the FAQ still not in the README? This is what most people tend to read first...
Kind Regards,
Remy
If in doubt, it helps reading the FAQ. See especially section "14.2.16. My standalone program does not work" ...
Best regards,
